Types and Associated Anomalies of Congenital Scoliosis / 대한척추외과학회지

ABSTRACT

STUDY DESIGN: Analysis was based on radiographic appearance of 57 cases of congenital scoliosis and associated anomaly PURPOSE: The aim of the present study was to assess the incidence, morphology and the associated anomalies of the congenital spinal scoliosis. SUMMARY OF LITERATURE REVIEW Hemivertebra is the most common type of congenital scoliosis and urogenital, musculoskeletal and cardiac anomalies are strongly associated. MATERIALS AND METHODS: The authors analysed the morphology and the associated anomalies of 57 cases of congenital scoliosis from 1994 to 2000. RESULTS: It was more common in male(32 males and 25 females). The bony anomalies were classified as failure of formation(40cases, 70.2%), failure of segmentation(11cases, 19.3%) and mixed type(6cases, 10.5%). Of the failure of formation, there were 36 cases(63.2%) of hemivertebra, 2 cases of posterior quadrant vertebra and 2 cases of wedge vertebra. We found associated anomalies in 26 patients(45.6%). Associated cardiac anomalies were 2 dextrocardia, ventricular septal defect, atrial septal defect and patent ductus arteriosus. Associated musculoskeletal anomalies were 5 rib fusion, 2 developmental dysplastic hip, 3 Klippel-Feil syndrome, Achondroplasia, Arnold-Chiari malformation, spinal dysraphism with sacral hair patch, cleft palate with congenital anklyloglossia. Associated neurogenic anomalies were 2 cases of syringomyelia and 3 mental retardation. There were unilateral renal agenesis and undescended testicle in urogenital anomalies. CONCLUSIONS: Common type of the congenital scoliosis was hemivertebra(63.2%) caused by the failure of formation(70.2%). Associated anomalies were found in 26 patients(45.6%).
